4.1.4 Cautions on target system design
• Do not place X1/OCD1A and X2/OCD1B next to each other on the target system.
• Make the distance between the target connector and the target device as short as possible.
• Since the X1/OCD1A and X2/OCD1B lines are used for clock supply, be sure to shield them, such as with a
